Absolutely. Good example would be Jim Chapin's Advanced Techniques for the Modern Drummer. At the beginning of each chapter - the initial exercises were all written as standard notation - then in a smooshed together version - to such just what you describe... The map of how the gears of it fit together.... the whole "together - RH - RH - LH - together - together" illustration.Having said that -- I do find using the stems-up version in the first few exercises in a beginner-level can be very helpful -- get students to think explicitly about how those limbs line up.
Essential for learning independence - but not at all practical for general reading. So once providing that key to get the process started - he quickly dispenses with it. Knowing that part of learning independence is learning how to look at two rhythmic parts and knowing how to fit them together. The instruction set for how to do that is something the player must learn to bring to the table when reading something.... just like piano players do. Actually just like we are expected to do with stickings - which are 99% of the time left to the player to figure out - or just know on the fly.
But once you move past the basics, you're thinking more in terms of rhythmic "words" or "sentences", not about the actual 16th note grid of each limb. Scan it quickly "oh, it's upbeats on the left foot". "8th and 2 16ths kick pattern". For me, the increase in scannability (specifically, it's SIGNIFICANTLY easier to pick out those "words" when you don't have to look "through" the hand notation to get to the note flag) is so extreme that I easily come down on the "100% bottom" camp.
Again for me - not 100% - but parts always stemmed in a way that maximizes that "being able to easily read the "words"" as you describe.
